I have an very old Kenmore top loader which after 20+ years still does
a great job. Over the years I've personally replaced the automatic
timer and the pump when they failed. However, lately I've noticed
large oil stains on my clothes after they have been washed. The
stains are not black and aren't noticeable until the garments are
dry. The oily stains are most conspicuous on dark colors. Other
posters in this forum have reported that, upon removal of the agitator
assembly, they found an oily goop on the agitator shaft . Cleaning
this gunk off the shaft seems to have resolved the greasy stain
problem.

Can someone please provide instructions on how to remove the agitator
from this machine. Do I need any special tools? Thank you.
